Title: Semiconductor light emitting device
Inventor: YAMAMOTO YOSHIHIKO
IPC: H01S5/00
Filed: 1988-03-11
Abstract: PURPOSE:To provide a light emitting device which enables single mode oscillation at a low cost, by oscillating the output light of an LD at single mode by two resonators and by using a lens for a mirror of an external resonator. CONSTITUTION:An LD is provided with two resonators by making a high reflection film 13 and a low reflection film 14 at an emitting end of an LD, and a lens 16 having a high reflection film 17 at the recessed side. Light oscillated from an LD chip 11 resonates between the high reflection film 13 and the low reflection film 14 in a chip, and light 15 emitted from the low reflection film 14 is converged by the lens 16 through the high reflection film 17 and incidented to a single mode fiber 20. Since the resonator length of an LD is specified at e.g., 300mum, an external resonator length 19 is calculated by adjusting the resonator length and the reflectance of reflection films 13, 14, 17 so that the lowest position of a loss curve comes into contact with a gain curve and light of single mode is output.

Title: Method and device for working lens
Inventor: NAKAMURA TERUO
IPC: B23K26/38
Filed: 1982-04-07
Abstract: PURPOSE:To work a lens uniformly with high accuracy and to simplify post- working, by cutting a lens blank material under rotation along the curve of the lens by means of a laser beam which focuses on the diametral line of said material while moving the beam in the direction orthogonal with the optical axis thereof. CONSTITUTION:A beam irradiating body 16 is so controlled that the laser beam emitted therefrom focuses on the optical axis of a lens blank material L. A horizontal guide base 7 and a rotating device 2 are moved to bring the roll 14 at the forward end of a detection rod 13 into contact with one end of a model body M. One end of the material L is located below the body 16. The device 2 is then driven to run a revolving shaft 6 at a low speed and the laser beam is irradiated from the body 16 to the material L so that the material L is fusion cut from one end on the outside circumference thereof. When the device 2 is moved toward the center by operating a hydraulic cylinder 10, the rod 13 moves the base 7 axially along the curve of the body M; therefore, the material L is cut from the outside circumference toward the central part in the diametral direction, whereby the lens having prescribed curvature is formed.

Title: Machine interpreter
Inventor: YOKOYAMA TAEKO
IPC: G06F17/27
Filed: 1983-03-31
Abstract: PURPOSE:To generate automatically the highly effective rules of sentence structure and to improve the operability of a machine interpreter by recognizing the combination of the array of sentence structure elements and the results of conversion in the form of a new rule of sentence structure when the frequency where the correct result of interpretation is obtained from existing rule of sentence structure exceeds a prescribed level. CONSTITUTION:The structure elements of an input sentence are successively written to an input sentence structure processing buffer 1, and the sentence structure is processed at a machine interpreting part 2. The initial element array of the input sentence structure discordant with the rules of sentence structure in the sentence structure processing mode is read into an initial sentence structure memory part 4 from the buffer 1. The part 4 is controlled by a sentence structure rule generating part 5, and the processing is newly applied to an input sentence structure conversion array which is not coincident directly with the existing rules and has a high using frequency as a new rule of sentence structure. This new rule is added to a sentence structure rule file 3. When the element array supplied to the buffer 1 is not coincident with the rules stored in the file 3 and correct conversion is possible with plural rules of sentence structure, the result of this conversion is controlled with each corresponding column of the part 4. Thus a highly effective rule of sentence structure is automatically produced.

Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which whiskers which are no problem in terms of quality are not recognized as a defect and in which an excessive inspection is prevented by a method wherein respective values which are obtained in an area computing process which computes the total area of islands inside a window on the basis of a specific expression and in an interval computing process are compared with a predetermined set value and a defect in a circular object is judged. SOLUTION: With reference to a closed-loop-shaped image which is obtained, e.g. from the cap 10 of a bottle, a closed-loop-shaped image which is contained in a fan-shaped region, at a vertical angle of m deg., whose vertex is nearly the center of the image is left, and a closed- loop-shaped image which is obtained in a fan-shaped region, at a vertical angle of n deg., adjacent to it is detected. Thereby, K pieces of windows, by an expression of K=360÷(n+m), which are arranged nearly in a circle are taken out. When the number of obtained images is more than a predetermined number, an amount which is related to intervals between a plurality of islands in the window in which the plurality of islands are contained is found.  In addition, the total area of the plurality of islands contained in the window in which the plurality of islands are contained is computed so as to be compared with a predetermined set value. Thereby, a defect in a circular object is inspected.
